Great men of action never mind on occasion being ridiculous; in a sense it is part of their job.

The term you are looking for is "fair use".

"In its most general sense, a fair use is any copying of copyrighted material done for a limited and “transformative” purpose, such as to comment upon, criticize, or parody a copyrighted work. Such uses can be done without permission from the copyright owner." http://fairuse.stanford.edu/overview...t-is-fair-use/

If you are selecting a few quotes to review a book or illustrate its contents for the reader, that is fine. Copying whole chapters or large sections of the book is straying from the definition and can get you in trouble.
